protection against contact.

Cable junction box for digital load cells PR 6024/68S 4 Installation and connection information

EN-12 Minebea Intec

When a fuse has tripped:

-Disconnect the junction box from all power sources.

-Determine and eliminate the cause of the error.

-Replace the fuse.

Make sure that fuses are replaced only using fuses of the same type, see Chapter 3.2.

-Reconnect the junction box to all power sources.

4.5 Cable gland

The cables have to be fed into the device via glands to ensure leak-tightness. Cable

diameters of 5…9.5 mm are suitable for gland M16.

The cable wires are connected to the terminals inside the device.

NOTICE

Property damage is possible.

If a cable gland is not used, it must be sealed with a supplied locking pin.

NOTICE

Property damage is possible.

Regularly check the tted cable gland for tightness and re-tighten it, if necessary.

4.6 Installation of a cable

NOTICE

Material damage is possible.

Do not guide the screen (4) into the device!

The cable shield (4) must be connected in the metal sleeve (6) of the cable gland.

Before, during and after installation, make sure that the sealing ring is seated

correctly.

5.1 General information

Cable entry must be from below.

Connect the wires to the terminals according to the color coding .

Connect all cable shields in the metal sleeve of the junction box cable glands, see

Chapter 4.6.

Establish potential equalization, see Chapter 5.4.

Note:

Chapter 5.3 shows an example of the cabling of 8 and 12 load cells via the PR 5510/04

interface and the PR 6024/68S junction box.

5.2 Data and supply cables

The PR 6124/xxD data cable must be used to connect the PR 6024/68S cable junction box

to the device, max. length: 300 m.

The PR 6124/xxP power cable must be used to connect the PR 6024/62S power supply to

the PR 6024/68S cable junction box, max. length: 200 m

5.4 Equipotential bonding conductor

NOTICE

It is especially important that the ground is connected correctly to the components

and the cable junction box.

You must also ground the device separately and ensure the power supply is properly

shielded against the eects of lightning. Simply connecting the protective grounding

conductor is not enough!

If the installation is not carried out according to our instructions, this voids the

warranty. In particular, the entire installation, including the power supply, must be

suciently protected against lightning.

In Ex areas, equipotential bonding must be established to avoid any compensatory

currents between the individual conducting system components.
